Burettes with Screw Type Rotaflow Stopcock with PTFE key

LABIX Burettes with Screw Type Rotaflow Stopcock and PTFE Key are high-precision volumetric instruments designed for titration and analytical laboratory applications. Built to Class ‘A’ accuracy as per I.S. 1997:2008, these burettes offer superior measurement accuracy, making them suitable for advanced scientific, industrial, and research environments.

These burettes feature a Screw Type Rotaflow Stopcock, which provides exceptionally smooth and controlled liquid flow. The PTFE key offers excellent chemical resistance, ensures leak-free operation, and prevents glass-to-glass contact, increasing durability and performance consistency.

Available in a wide range of capacities—from small volumes (1 ml, 2 ml, 5 ml, 10 ml) to standard laboratory sizes (25 ml, 50 ml, 100 ml)—each burette includes fine subdivisions and low tolerance limits for precise liquid dispensing. Certain models also include a cup top for easy filling.
